| Abstract: | ABSTRACT Introduction Approximately 3–7% of advanced non-small cell lung cancers (NSCLC) are driven by an anaplastic lymphoma kinase (ALK) rearrangement. Crizotinib, ceritinib, alectinib, and brigatinib are active ALK inhibitors (ALKi) used to treat this oncogene-driven subset of NSCLC. Resistance occurs with time to ALKi and new therapeutics are being developed. Lorlatinib is an efficacious third-generation ALKi with an ability to overcome resistance mutations that develop with first- or second-generation ALKi. |
